Connecting calibre to BQ Aquaris M10 FHD via MTP

I have many books that I would love to peruse on the BQ Aquaris, but unfortunately, I cannot navigate to the "Books" folder I created on my tablet through calibre to set up a manageable ebook repository, as it uses the MTP pr.otocol.

I have not been able to find a guide to connect calibre to that specific folder on my MicroSD Card, so I am wondering whether anyone in the community knows a way to do it.

@rewarp I'm not really following you here and maybe others have the same problem. What is calibre? I can't find it in the app store. How are you trying to navigate where? Please describe your challenge in different words and with more detail.

Sorry for the lack of clarity. calibre is a cross platform ebook manager. It has a feature that allows users to manage their ebook collection on various connected devices. It has a repository of recognised devices built-in so most ereaders like the Kobo or Kindle reader can be connected without hassle.

For unrecognised devices, it is possible to designate an ebook folder on a devices through calibre so that ebooks can be transferred and managed with ease.

I created an ebook folder on the MicroSD card because it is likely to take up a lot of space. Unfortunately, I cannot figure out a way to navigate to that directory from calibre as the connection uses the MTP protocol. So the address is mtp:/[path-to-folder], instead of /media or something equivalent.

@advocatux Just to test it wasn't my external sd card, I tried to connect to a storage folder on the internal sd card. It doesn't work because it is an mtp connection, and it is apparent that calibre for now is not set up for mtp with the M10 FHD.

I am running openSUSE Tumbleweed for my calibre library. There is no sudo mtp-detect command

Yes. It's on a 5 minute timer before auto-locking.

I am not running any program with sudo unless I am 100% certain I won't accidentally screw up assignments of files and folders. I learnt that years ago with "sudo firefox". Reassigning ownership for 2500 ebooks is something I am not keen on doing.

1.- You need to install mtp-tools http://software.opensuse.org/package/mtp-tools
2.- Just for testing, try it with all the unlocking you can, including developer mode.
3.- Good. Never run any command or script if you don't fully understand it. Said that, reassigning ownership for 2500 ebooks only takes a few seconds with chown command.

Forgive me for being a bit chuffed. I know what sudo calibre does. I also frequently employ chown as well. What I do not understand is the need to run calibre as sudo just to get file transfer working (if that will even work) when I can transfer files to my android and LineageOS devices without involing sudo. I would appreciate more detail on what the intention is before I execute the command.

@rewarp, maybe you want to edit your serial number ;) Just put some XXXXX

I've made a quick test connecting a Debian box to my Ubuntu phone and Calibre fails to write to the sd card. However I can write to the sd card using mtp directly (v.g. making a directory named "Books").

It seems Calibre have a problem with read/write perms.

I'll try to check this out when I have more available time, sorry.

I forgot to comment that if Calibre sees your device, you can click in "Card A" and in the dropdown menu there's an option to specify a directory (folder).

Yes, I have already mentioned that I can write to the SD Card directly. My problem is I cannot get calibre to do it through its interface.

As an addendum, I guess I will wait until the transition to Ubuntu 16.04 for my tablet before filing a bug report to calibre upstream. I wouldn't want the developer to spend time on a platform that is about to be deprecated.
